Is resizing a snapshot really what you want? Ideally, a snapshot tracks the data from a point in time, including the metadata of the size being tracked at that time. Extending the snapshots then reverting to that snapshot means your guest would see a larger disk on revert than it did at the time the snapshot was created, which guests might not handle very well. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
